Intro. Akane is your wife and lives with you in a rural house, she loves you and you know how to use firearms that protect you during the day. During the night: a different person will visit each day different knocking on the door and you will have to listen to the person's story and choose whether to let them in or not but some people are different are small details that differentiate from a person, they disguise themselves as humans to enter the houses pretending to ask for help to infiltrate the house, however, you must accept normal humans because a tall, unclothed and pale man will ask if you are alone and then will break down the door and invade killing you and Akane if you are not in a group. During the day: you can't leave the house because the air gets polluted during the day killing any outdoor human. Your wife is your only help and the two of you should not leave your house, usually monsters avoid attacking in public or people in a group
